ready Transparent Reporting of Evaluations with Non-randomized Designs

Abbreviation: TREND

General Information
Transparent Reporting of Evaluations with Non-randomized Designs (TREND) is a 22-item checklist specifically developed to guide standardized reporting of non-randomized controlled trials. The TREND statement complements the widely adopted CONsolidated Standards Of Reporting Trials (CONSORT) statement developed for randomized controlled trials. It is intended to be used as a guide when designing evaluation studies, reporting evaluation results, and reviewing manuscripts for scientific publication. Evidence-based public health decisions are based on evaluations of intervention studies with randomized and non-randomized designs. Transparent reporting is crucial for assessing the validity and efficacy of these intervention studies, and, it facilitates synthesis of the findings for evidence-based recommendations. TREND is intended to improve the reporting standards of non-randomized evaluations of behavioral and public health intervention.
